This week appears the first map of the genetic biodiversity of butterflies of the Iberian peninsula. The work has been led by Roger Vila, a CSIC scientist at the Institute of Evolutionary Biology (Institut de Biologia Evolutiva-IBE) ...

In an article published today in the journal Nature Communications, researchers from the University of Bergen (Norway), IRTA Institute of Marine Sciences of the Spanish National Research Council (CSIC) and Institute of Evolutionary ...

(Phys.org)—Standard evolutionary theories of aging and mortality, being based on mean-field assumptions – which analyze the behavior of large and complex stochastic models by studying a simpler model – conclude that ...

(Phys.org)—Over long spans, biodiversity is a fluid and shifting balance of species and influences. Species diversification occurs in response to a host of complex factors, both biotic and abiotic, and understanding them ...

Fish are power eaters. In many species, large muscles running along their backs and bellies provide bursts of speed for chasing down prey. Then, at the very instant they close in, they vacuum victims into their suddenly gaping ...

Ten subsocial cobweb spider species were discovered in a research on nearly 400 Madagascan colonies, conducted by Dr. Agnarsson's team. Most of them are single forest endemics and belong to one genus, Anelosimus.

The American mathematician John Nash, who died in a taxi accident at the weekend, is probably best known to the wider public through Russell Crowe's portrayal of him in the 2001 movie A Beautiful Mind.

Evolutionary biology

Evolutionary biology is a sub-field of biology concerned with the origin of species from a common descent and descent of species, as well as their change, multiplication and diversity over time. Someone who studies evolutionary biology is known as an evolutionary biologist.
